记者从中国科学技术大学获悉,该校自旋磁共振实验室教授王亚等与浙江大学海洋精准感知技术全 国重点实验室合作,在纳米尺度量子精密测量领域取得重要进展,首次实现了噪声环境下纠缠增强的纳 米尺度单自旋探测。相关研究成果于北京时间11月27日在国际权威学术期刊《自然》在线发表。 在微观世界中,电子的"自旋"是其基本属性之一,如同一个个微小的磁针。材料的许多宏观特性, 如磁铁的磁性或超导体的零电阻,都源于这些微观"磁针"的排列与相互作用。 金刚石氮-空位色心量子传感器,因其纳米级的分辨能力和高灵敏的磁探测能力,一直是实现单自 旋探测的重要技术途径。研究团队朝向单自旋探测的科学目标,通过长期积累,发展出高精度的自旋量 子调控技术和金刚石量子传感核心器件与装备,在前期工作中已能通过频谱差异识别出那些带有特 殊"标记"的单自旋。 研究人员介绍,十多年来,研究团队着力于高品质金刚石量子传感器的自主制备,打通了涵盖二十 多道环节的完整工艺流程,掌握了其中的关键工艺。他们通过材料制备与量子操控两条路径的协同创 新,首次成功开发出纠缠增强型纳米单自旋探测技术,在固态体系中实现了对微观磁信号灵敏度与空间 分辨率的同步提升,为纳米尺度量子 ...

Group 1: Development of Embodied Intelligence Industry - The National Development and Reform Commission (NDRC) aims to promote the healthy and standardized development of the embodied intelligence industry through three main strategies: establishing industry standards and evaluation systems, accelerating key technology breakthroughs, and promoting infrastructure construction for training and pilot testing [1][2]. Group 2: Human-shaped Robot Market Insights - The human-shaped robot industry is experiencing rapid growth, with a predicted market size reaching 100 billion yuan by 2030, driven by innovation and demand [2]. - There are currently over 150 human-shaped robot companies in China, with more than half being startups or companies from other sectors, which raises concerns about product redundancy and market saturation [2]. Group 3: Six-Dimensional Force Sensor Market - The market for six-dimensional force sensors, crucial for real-time precise force control in human-shaped robots, is witnessing explosive growth, with an expected shipment of 12,300 units this year, a year-on-year increase of 510.1% [3]. - The market is becoming increasingly concentrated, with leading companies holding over 70% market share, specifically Blue Dot Touch with a market share of 72.6% [3]. Group 4: Infrastructure REITs Expansion - The NDRC is actively promoting the expansion of infrastructure Real Estate Investment Trusts (REITs) to include urban renewal facilities, hotels, sports venues, and commercial office facilities [6]. - The NDRC plans to enhance collaboration with the China Securities Regulatory Commission to optimize project application processes and support more eligible projects for issuance [6]. Group 5: Special National Bonds for Investment Projects - The NDRC has allocated 80 billion yuan in special long-term bonds to support 1,465 and 1,459 "hard investment" projects in the last two years, reflecting a strategic and forward-looking approach [8]. Group 6: Growth of ETFs in the Market - The number of billion-yuan ETFs has reached a historical high of 119, with the total market size of ETFs at 5.69 trillion yuan, indicating a strong trend in the ETF market [10]. - The majority of new billion-yuan ETFs are bond ETFs, with significant contributions from major players in the market [10].
